|Title of Invention||
ANTI SABOTAGE DEVICE
|Abstract||An anti sabotage device used in the fish plated joints of railway track comprising at least one nut and fish plate bolt to join the rails, a key for operating the:-device and - characterized in that the bolt will go up to 45mm inside the nut after tightening with key and the said nut is provided with taper shape so that it is impossible to hold with any of the existing tools for tightening and loosening.|
The Present Invention "ANTI SABOTAGE DEVICE" relates to specially designed system which is used in Fish Plated Joints of Railway Track, which cannot be removed with any of the existing tools/devices available in the general market.
Disadvantages of Existing Systems:
Any miscreant with any spanner can remove the existing Fish Plates Bolts and Nut very easily. Due to the removal of the Bolt and Nut, many accidents are taking place frequendy in order to overcome the existing sabotages, the present invention, which is unique in its own, is made by the inventor.
ADVANTAGES OF PRESENT INVENTION:
a) The New Device can be operated with duly designed key exclusively designed for this purpose.
b) Only authorized track maintenance staff can operate the device.
c) The existing structure is not altered, but the device is fastened to fish plate bolts at the Nut End as a replacement of present Nut.
d) The Internal diameter of the device is the same of that of the existing Nut.
e) The same spanner can be used on this device.
f) Railways need not go for additional tools for operating the
g) The Device is totally prevents the removal of the Fish Plates
by Un-Authorised person.
h) The Design of Each batch of the Device can be modified, revised to suit Railways requirement.
DESCRIPTION/EXPLANATION TO THE DIAGRAMS:
^) Fig -1 Shows about the Nut, which is fitted, to the fish Plate Bolt that Joins the Two Rails. Every Fish Plate has four holes with Bolt and Nuts. Miscreants can remove the ordinanry Bolts or it may fall down due to vibration in the track. The said Anti Sabotage Device Nut has got its own Special Design developed by the inventor.
The "A1' Side having threads will go into the existing bolts on the track. The bolt will to up to 45 mm inside the Nut, after tightening with key.
The "A2" Shows the end side of the Anti Sabotage Device Nut it is a special design for inserting the special key for tightening and
loosing the nut from the end side. It will not allow any other spanner/tool except the special key inside the nut.
The "A3" The shape of he Anti Sabotage Device Nut is given taper shape so that it can not hold with any of the existing spanner / tools for tightening or loosening the nut. This is a unique concept of the Device.
The "A4" Shows about the pin which will be inserted from the thread end side and it will be obstructing any other spanner/tool to enter at the nut end side. It will allow only the special key for operating the Anti Sabotage Device.
Fig — 2 Shows about the Special Key, which has to be inserted in "A2" end of figure.
"F 1" for tightening and loosening the Anti Sabotage Device to the bolt. It will go up to 20mm inside the Nut and holds for tightening and loosing of the nut.
"F 2" this is made in the shape of hexagonal to hold with the spanner which is presendy used by the points man for tightening and loosening the Anti Sabotage Device. After tightening / loosening the key will be removed and will be kept with the points man. The Anti Sabotage Device cannot be tightening or loosening without the key.
1. An Anti Sabotage Device used in the fish Plated
Joints of Railway Track comprising at least one nut
(fig-1) and fish plate bolt to join the rails, a Key
(fig-2) for operating the Device Characterised in
that the bolt will go up to 45mm inside the nut
after tightening with key and the said nut is
provided with taper shape so that it is impossible
to hold with any of the existing tools for tightening
2. An Anti Sabotage Device as claimed in claim I
where in every fishplate has four holes with bolts
